Keith Urban says Taylor Swift was "amazing" when she opened for him on tour as a teenager.
The country singer hit the road with Taylor back in 2009 when she was the opening act for his 'Escape Together World Tour' and he's admitted he knew she had something special long before she became a global superstar.
During an appearance on 'The Jennifer Hudson Show', he said: "It was a long time ago obviously ... yeah it was great. She was amazing even back then.
"I would sit up front and watch her sing and I'm like, 'Oh, she was singing way off into this other thing.' You could see it. She was playing way past where she was already. It's amazing."
Keith also revealed how Taylor pranked him on the last night of the tour by coming out on stage dressed as KISS rocker Ace Frehley.
He said: " There was a prank she did. So I have a song called 'Kiss a Girl,' and on the last night of the tour, she came out dressed as Ace Frehley from the band KISS. I thought it was KISS for a minute. It was so good."
The pair ended up collaborating on a song together when Keith provided vocals for her track 'That's When' which was featured on 'Fearless (Taylor's Version)' and he also sang harmonies on 'We Were Happy' on the same album and the country star has revealed he was thrilled to be invited to sing with her.
He added: "She had a song she wanted me to do, and she just texted me and said, 'I have a song that I want you to sing on,' and I said, 'Can you send me the song?'
"The next minute, she texted me the song. I was in a food court at a shopping mall at the time. I'm sitting there with my AirPods in listening to this unreleased Taylor song. It was crazy."
